# update_knowledge_section

Update a specific section of a knowledge file by its ## header. If the section exists, its content is replaced. If it doesn't exist, it's appended as a new section. Use this for surgical edits to guidelines or strategies without rewriting the entire file. [write-tier — first use may require a manager's approval; a from-now-on approval makes future calls seamless, a just-once approval re-asks next time.]

## Why update_knowledge_section is rated Medium

This tool modifies knowledge file content by updating or appending sections, which is a Write operation—reversible data modification. It is not Destructive because sections can be reverted and the entire file is not deleted. Severity is medium because misuse could corrupt business guidelines or strategies, affecting team operations, but the impact is limited to a single section and is recoverable.

From the tool's own definition: "Tool description explicitly states: 'If the section exists, its content is replaced. If it doesn't exist, it's appended as a new section.' This is reversible modification of knowledge files. The write-tier notice confirms it creates or modifies data."

## Use case

AI agents use update_knowledge_section to create or update resources in Freedom Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Freedom Mcp environment.
